in the steam forums, i heard there was pages and pages and pages of complaints and discussion on it, as much as a new page of posts per SECOND, with no one knowing why, and it was supposed to come out yesterday at 1PM CST and was pushed back 10hrs was the announcement made, not 4.

for the record i have no opinion on the subject as i don't EVER plan on buying L4D2, so good luck waiting with baited breath for the 'demo'

I don't understand why people complain so much when it comes to this game. I played the crap out of the first one and got my moneys worth. I'm sure I am going to play this for just as long, maybe longer. So you had to wait a few hours. If you are waiting at a computer for a game demo to be released and can't find anything else to do, maybe that's the problem not the demo being delayed. Don't mind me I'm just complaining about complainers.
